Sell Solar LCD Car TPMS SP370 Wireless Tire Pressure Monitoring System With 4 External/Internal Sensors best price

Solar LCD Car TPMS SP370 Wireless Tire Pressure Monitoring System with 4 Sensors Description: - Tire pressure alarm, wireless transmission; four wheel simultaneous monitoring on the color display - Prevent problems before they occur: prevent puncture and air leak to balance air pressure, save fuel, and reduce wear - With 4 external/internal sensors External sensors - Easy to install - The battery life is about two years, and the battery can be replaced (installed on the valve core) - Anti-corrosion coating on the surface of the casing - Hexagonal nut anti-theft patent - Patented silicone integrated molding structure with unique external tire pressure sealing and ventilation to prevent air leakage Internal sensors - The battery life is about five years, and the battery can be replaced (replace the original valve core, balance after installation). - Aeronautical road alloy gas nozzle - Quality battery - The casing is made of nylon chemical fiber to prevent corrosion - An adjustable angle link between the nozzle and the sensor ensures that the angle is adjusted to be flush with the edge of the wheel - Professional installation is recommended Tire pressure sensor module working state Because the tire pressure detection module is powered by battery, the battery life problem becomes a problem that needs to be considered, especially in software design. The low-power algorithm implementation should be carefully designed and can be roughly divided into the following states: - Storage status: The system is in an unused state and it should enter deep sleep mode - Transportation status: The detection module has been loaded and is not actually used during transportation. - Parking status: Activated and started working, but stopped at this time, the speed is 0 - Driving status: Through the acceleration sensor, the speed change is detected, the running state is entered and the tire pressure, tire temperature, speed, etc are detected. - Low voltage status: If the battery voltage is too low, continuing to work will cause the related functions not to work properly, and a warning will be issued. - Leakage condition: A tire leak is detected by continuous inspection, and a warning is issued. Feature: - High-efficiency solar panel, superior long duration capability - Large-capacity built-in metal lithium battery - Accurate monitoring of tire pressure stability values all the way - High precision LCD display - Large volume alarm sound alert - A variety of tire pressure units are available - Long receiving distance with stable signal - Support tire position interchange Function: Real-time monitoring: The tire's pressure and temperature status can be monitored regardless of whether the vehicle is running or at rest. The tire status is under control. High pressure/low pressure alarm: When the tire pressure is higher or lower than the set value, the system will give an alarm. Air leak alarm: The system will give an alarm if a foreign object penetrates into the tire an
